AFAIK Metapost only outputs EPS or SVG with *unstroked* paths i.e. the
actual outlines of the strokes are themselves never output. Only the
central path is output and the actual blackened pixels are only ever
computered by the final rasterizer. In case of elliptical/rotated
pens, appropriate transforms are added to the paths so that the final
output *seems* as if it was drawn by such a pen.
